Hello everyone,
thank you for this tread...
I have the same exact issue as
@mlladen996 describes in his initial post.
I have a Powercolor Radeon VII (also second hand)
GPUz shows the exact same, LITERALLY IDENTICAL (ie, finds card, bios version, ROPs/TMUs, shaders...but pixel/texture fillrate unknown, memory size 0mg, clock speeds 0mhz)
I can add that on GPUZ v2.33....it additionally shows HBM2 (Micron) ....as oppose to just HBM2 as in
@mlladen996 initial post
Also getting Error code 43 in windows (when i put an older nvidia card in PCIe slot 1)
I have tried all the DDU/driver updates etc as described above...
I have also tried
@eidairaman1 ATIflash methods. The card is recognized by both the windows & dos versions of ATIflash, and has accepted very bios I have tried (all from this website). The card came with bios v105, and its the same story when I flash v106
With just the Radeon Vii in PCIe slot 1, I can not get any video output...
fan & lights on the video card come on...
Lenovo D30 Workstation (type 4223)...is the computer/motherboard I am trying to install this card in...
it has a Bios POST code LCD built into the motherboard --> shows system hangs on POST code B2...
from what I've googled, post code B2 usually represents VGA check failed...and interestingly when I put my other older nvidia card in, I can see the motherboard cycling throught the post codes, and momentarly pauses on B2, then the screen come on and the computer continues through various other post codes until it settles in AA when working...
I've also checked out Eli Tech on youtube (he's awesome) and did the same as
@mlladen996 , opened the card up....
the main gpu chip does get hot, and I can verify i get the same voltages on the various phases and chips... so the board seems okay (?)
I called AMD... they mentioned some workstation mainboards don't work well with AMD chipsets and suggested I ask Lenovo (waiting on a response...)
In the Bios I noticed various PCI settings:
- PCI latency timer
- VGA palette snoop
- PERR# generation
- SERR# generation
- PCI Express Settings --> ASPM support, Link Training Retry, Link Training Timeout (uS), and unpopulated links...
Wondering if any of these might have a role??
Also going to try to take the card to a repair shot or best buy to see if I can test it on a newer, known to be AMD compatible, motherboard....
If anyone has any tips or suggestions please do respond...
